- Seven-Part Series Narrated by Alec Baldwin and from Makers of PLANET EARTH
Premieres Sunday, March 18 at 8PM -

Like a lightning bolt hurled down from Mount Olympus, an icy "finger of death" strikes at sea life beneath the Antarctic ice shelf in what is surely one of the most jaw-dropping natural history sequences ever filmed.

Called a brinicle, or brine icicle, this sinister tube of ice grows over a matter of hours as brine leeches from the forming sea ice above. This video - a scene from FROZEN PLANET, premiering on Discovery Channel on March 18 - illustrates how this happens, as well as the consequences for the slow-moving marine invertebrates in its path.
